My invention is concerned with pipe sleeves, such as are used in concrete or other nre-proof -iioors and walls, and with a novel 'extension for saidpipe sleeves, adapted to be secured to the ends of said .sleeves after the concrete is set to form a finishing ring, and which can be adjusted onA said pipe sleeve to center it on the pipe, which lit surroundsfeven if the pipe,as is frequently the -case,.be not. concentric with` the pipe sleeve.v

To illustrate my invention, I annex hereto two sheets of drawings, in which thevsame reference characters are used to designate identical parts 4inzall thefigures, of which,

1 and 2. f :In: .the modern practice of constructing reiniorced concrete buildings, provision is made for passing .the piping necessary for` plumbing of all sorts through the Vwalls and floors by securing :pipe .sleeves at the necessary places on the part .of the false work or frames that form the walls, or more frequently the flooring so that when the concrete is poured and set, and the false work or forms vfinally removed, the walls or floors, as thefca'se. maybe, will haverusually circular aperturestherethrough lined by-the metallic sleeves employed. So far as my present invention is concerned, ,these sleeves 22 imbedded in the concrete 2|, as shown in Figs. 1 to 4, may be of any desired shape and material, although in the pre` erred form they areof sheet metal and have near the bottom at least a transverse annular `groove r35 formed on the interior, which acts as a strengthening rib in the manner that will be readily understood. In my present invention, 1 employ with the sleeves, extension membersv 40,

into'the apertures 55, thereby securely holding one form of which is shown with the four parts thereof detached and in perspective in Figs. and 6. The holding portion shown in Fig. 5 is. made up of two identical sheet-metal sections lll, gen'- erally semicircular in outline, with one endrhavf A5 ing a rectangular aperture l2 therein,.whi1e the other end is provided with an extension i3 formed from thesheet metal and having the downwardly projecting tip lll adapted to snap into the aperture l2 of the associated half. To- 10 ward the ends of the part M, they are turned under at Il5 to form a groove adapted to receive the anges HG of the extension members lll, shown detached in Fig.. 6. These members il are, in the form shown in Fig. 6, made up of the semicircular main portions i8 having the flanges E5 extending horizontally therefrom, as shown, which are connected with the reduced lower portions 49 by the inclined portion 5E), which may have the aperture 5l therein, for a purpose to be `20 hereinafter described. The portions l5 have at one end the inwardly offset tongue 52, and the portion 159 has at the other end the inwardly offset tongue 53. The bottom of the portion i9 is preferably formed with the curved flange 55 hav- 25 ing at one end an aperture 55 andat the other .end the inwardly-offset, curved tongue 55, which .has projecting outwardly therefrom the lug` 51. Where the extensions are to be employed with pipe sleeves having the internal annular grooves 35,-1 form on the members lll the upwardlyprojecting tongues 58 terminating in the humps 59 formed by shaping the ends of the tongues 5B as shown. These tongues are adapted to enter the bottom grooves in the sleeve holder when lv35 the parts are'assembled, and it will be under- .stood that in-assembling the parts, the two halves shown in Fig. 6 are rst brought together around the pipe, and when brought together, the tongues 52 will fit inside of the members i8 of the oppos- "40 ing halves, and similarly the tongues 53 will t inside of the opposing portions 59, and the tongues 55 will t in the grooves 54 of' the opposed halves, and the projections 5l will snap ,45

the two halves together. With the extension half thus assembled below the sleeve, the two vhalves shown in Fig. 5 are then slid in place over the 'flanges 46, which enter the grooves 155, and the ends 44 of the tongues 53 snap into the apertures 42, so that the assembled extension can now be shoved upward so that the tongues 58 will extend between the pipe and the sleeve, and

enter the grooves 35 and securely hold the parts in place.

The purpose of the sliding connections between the upper and lower portions of the extension is indicated in Figs. l to 4 and '7 and 8, where it will be seen that the pipe 6@ is sometimes concentric with the sleeve and sometimes not. Where it is not concentric, the lower half can be slid on the upper half until the extension is concentric with the pipe, and it will be obvious that the entire extension can be rotated when necessary to secure the desired exact concentric relation of the extension to the pipe.

In Fig. 6, I have illustrated the aperture 5l formed in each of the extension halves, Vand where the pipe sleeve does not have the internal annular grooves in which the humps 59 t, I contemplate securing the extension in place by sheetmetal straps or wires, the lower ends of which would pass through the apertures 5I and be turned to hold them in place, and the upper ends of which, similarly, could be turned over and caught in any desired manner on the upper surface of the concrete.

Where this particular form of extension shown in Figs. 5 and 6 is employed, a finishing coat of plaster 6l is frequently applied, and in that case I will place in the upper portion of the extension, between the concrete and the offset portion 50, packing 62, which will serve to shut out the noises between the iioors, and also the passage of dirt.

Where insulation tubing 63 is employed about the pipes 65, as shown in Figs. 3 and 4, I modify the shape of the lower half to the form 111a shown, where the offset 50 is not employed and it is approximately a true cylinder.

While I have herein shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.
